【Docker 系列】docker 学习六，数据卷容器

1. Dockerfile格式

Dockerfile格式

2. Dockerfile指令

Dockerfile指令

3. Build镜像

Usage: docker build [OPTIONS] PATH | URL | - [flags]
Options:
-t, --tag list # 镜像名称
-f, --file string # 指定Dockerfile文件位置

docker build .
docker build -t shykes/myapp .
docker build -t shykes/myapp -f /path/Dockerfile /path    ---最常用，指定本地Dockerfile文件
docker build -t shykes/myapp http://www.example.com/Dock

4.4快速部署LNMP网站平台

LNMP具体流程

自定义网络
docker network create lnmp
创建Mysql容器
docker run -d \
--name lnmp_mysql \
--net lnmp \
--mount src=mysql-vol,dst=/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
创建PHP容器
docker run -d --name lnmp_php --net lnmp --mount src=wwwroot,dst=/wwwroot php:v1
创建Nginx容器
docker run -d --name lnmp_nginx --net lnmp -p 88:80 \
--mount type=bind,src=$(pwd)/nginx.conf,dst=/usr/local/nginx/conf/nginx.conf --mount src=wwwroot,dst=/wwwroot nginx:v1
以wordpress博客为例
https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz

[root@docker ~]# docker network create lnmp
